NONSKID DEVICE.

Beit known that I, TRUE M. AVERY, a citizen of the United States, residing at Glens Falls, in the county of Tai-ren and State of New York, have invented new and useful Improvements in Nonskid Devices, of which the following is a specification.

This invention relates to improvements 1n non-skid devices for vehicle wheels, proposing a device which is intended to secure the non-'skidv element, i. e. the cross chain, 1n

anchored relation and which is especially i applicable to so-called steel wheels, that is to say, wheels which are without spokes and whose structure includesdisc-l1ke side plates to which. the hub and felly are secured. y l

The principal objects of the invention, briefly stated, are to provide a non-skid device for use las described which maybe manipulated with quickness and facility in putting on or taking olf the .non-skid element, which effects the certain and reliable securement of said element and whose parts for the securementof said element take up a minimum degree of space at the sides of the wheel.

With the above objects in view the invention consists in certain novel' features of structure Vand relation appertaining to the combination of two hook' parts for arrangement atV opposite sides of the wheel to secure the terminal links or eyes of the nonskid element and'also in certain novel fea-y Figure 3 is a frontelevation of the same.

Figure 4 is a front elevationV of the com,- panion cooperating hook part. i

vSimilar characters of reference designate corresponding parts Vthroughout the several views. Y

The improved device consists oftwo companion elements 1 and .2 for attachment to planes transverse tofthe wheel.

the wheel at its opposite sides. The inven- `tion is applicable to so-called steel wheels of various constructions and which embody annular side-plates A and B connected to the hub and the felly. Figure l shows these side platesA as provided with shoulders C of angular cross-section which may be formed at regular intervals and which have perpendicular walls D; and in the construction disclosed the elements 1 andr2 are secured to the walls D.

Each ofthe companion elements includes a flat base 3 provided with apertured termi- -nal ears 4 for its attachment to the wall D. Any suitable fastening means may be elnployed for the attachment of the elements 1 and 2, forexample, fastening bolts 5 which extend transversely through the` wheel and are common to each pair of cooperating elements. The elements 1 and 2 are provided with single hooks, 6 and 7 respectively. These hooks are located centrally of the bases 3 and project laterally from said bases in According to theinvention, the hook 6 cooperates with a movable guard or closure 8 while the hook 7 is devoid vof a movable guard or closure but is recurvate, that is to say, its terminal 9 is directed back or inward toward the base 3, an open chain link passage being left bctween said lterminal and base. ln the construction preferrcd, the hook 6 is devoid of krecurvate formation, that is to say, its terminal portion is presented perpendicularly; and the chain link passage between the terminal of the hook 6 and the base 3 is nor-V mally closed by the guard 8. The guard S may be of any suitable construction for the purposes in View, but it is preferably similar in general respects to the construction shown in my copending application Serial No. 147,856and is so disclosed. As shown. saidguard consists of a sheet metal part of channel cross-section provided with laterally arranged resilient terminal lips 10 for frictional engagement with a cooperating lug 11 provided on vthe base 3. The lug 11 is preferably of round cross-section and -is of greater diameterthan the normal spacing between the lips 10 whereby said lips may be sprung past the portion of said. lug of greatest diameter and will thereafter press inward on the lug. The guard 8 is pivotally mounted at its end remote from the lips 10 iupon a supporting lug 12 and is, therefore,

movable to av position wherein it closes the link passage between the hook 6 and the base 3 and its lips 10 are rictionally engaged with the lug 11 to securethe guard in such |position or to a position wherein the said link passage is open and the terminal link may be freely disengaged Jfroml the hook 6.

In the construction disclosed and with reference to certain specilic details compre-V its sides with shoulders 14 which, when the guard 8 resumes its closed position, are engaged by the side portions 15 of said guard and are thereby effective to limit its downward or closing movement. The freeend of the guard 8 is preferably of open construction, as shown in Figures 2 and 3, so that when the guard is closed, a clearance vor opening 16 is provided which is utilized in connection with the opening of the guard. Thus, a screw driver orany suitable implement may be inserted through the opening 16 and with its end held in the angle forme by the lug 12 with the upper face of the projection 13 may be manipulated against the upper or connecting wall oi' the guard 8 to raise said guard sufficiently to disengagethe lips 10 from the lug 11.

The non-skid element, i. e. the cross chain E, is anchored to the wheel by means of the Y hooks 6 and 7 with which its terminal links are-engaged. To secure the cross chain .its-

terminal link at one end is engaged with the hook 7 and, the guard 8 being in open position, its link atV the other'end is `engaged with the hook 6, after'which the guard 8 is moved to its closed position, its lips 10 snapping over the lug 11 and cooperating therewith to hold the guard closed. To remove the cross chain the guard 8 is raised and the terminal links are disengaged successively "from the hooks 6 and 7. Y

The arrangement of the guard 8 whereby, when closed, it projects laterally over the hook 6 is of advantage from the,` standpoint orV accessibility in connection with the manipulation of the guard 5v and in connecltion with such arrangement-y of the guard 8 the lug 11 is also arranged to overhang the hook'and to project slightly below the guard. As thus arranged the lug 11 will provide a rigid abutment against which the terminal link. will exertthrust vunder some condition of "its forcible displacement that may be encountered in use, i. e., during the normal rotation of the wheel; and in this way the lug 11 protects the guard 8 from any pressurewhich might result in its accidental opening.

The perpendicular relation oi' the terminal portion of the hook 6 promotes facility in securingand removing the cross chain while the reliability of the securement of the cross chain is provided for by the positive closure of the liook6, as by the guard 8, and by the recur-vate form oi' the hook 7, the overhanging relation oi' the terminal 9 preventing the accidental disengagement of the link which is secured by the hook 7. n

As shownl and preferred the element 1, which has ythe guard 8 is arranged at the outer side of vthe wheel where there are no obstructions and where the guard may be manipulated with facility and the element 2 is arranged at' the inner side of the wheel where the presence of obstructions', such as the` brake drum F, does not involve any problem,-owing to said element being devoid of a guard or of movable parts.

I claimz- 1. In a non-skid device for vehicle wheels, a chain-link-securing part comprising an attachment base anda single hook projecting laterally therefrom with a link passage between said base and the terminal of said hook, a pvoted guardto close said link passage andmov'able in a Vcommon plane with said hook and a lug projecting from said base in overhanging relation to said hook for frictional securing co-operation with said guard vwhen the latter is in position to close saidlink passage,I saidlug pro-` jecting beyond 4the guard, i when closed, towardthe base of said hook. i

2. In a non-skid device for vehicle wheels, a chain-link-securing part comprising an attachment base and asingle hook projecting laterally therefrom-with a link passage Vbetween said base and the terminal of said hook, said base Ahaving'aprojection along its edge and from its'sideopposite to the edge and side fromwhichsaid hook projects,

an upright lug on said projection, a second lug projecting from said base in overhanging relation 'to said hook, and a guardpivoted tosaid upright lugand movable'in a Vcommon plane with'said hook into overhanging relation to said hook-to close said 1 y i link passage, said'guard near its Youter Aend having secured cooperation with said second lu Y f.

In testimony whereof I have hereunto set my hand in presence of two subscribing Y THiiRns M, KENA, Y
